Abstract (en)

[origin: EP3054363A1] The present invention provides a configuration which enables an improvement in the workability of wiring of a sensor in a servo system. An encoder (31) detects the operation of a motor (30) driven by a servo driver (2), and generates a feedback signal (FB) indicating the detected operation. Further, the encoder (31) receives detected signals (DET1 to DET4) output from sensors (61 to 64) for detecting an object (53) driven by the motor (30) via sensor cables (71 to 74). The encoder (31) outputs the feedback signal (FB) and the input detected signals (DET1 to DET4) to the outside.
